Molecular Weight: 108.14 g/mol
Inhalation: Move affected person to fresh air, monitor breathing, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, wash skin thoroughly using soap and flowing water, seek attention if irritation develops
Eye Contact: Rinse opened eye(s) under gentle stream of water for at least 15 minutes, keep eyelids apart, removal of contact lenses advised, consult medical professional
Ingestion: Rinse mouth, drink a moderate amount of water, avoid inducing vomiting, seek help at poison control center or emergency medical provider
Most Important Symptoms: May include moderate stinging to eyes, reddening of skin, possible headache or drowsiness with high vapor levels
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, sand; avoid direct water stream
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, possible traces of toxic pyrazine derivatives on incomplete combustion
Fire/Explosion Hazards: Vapors can ignite above 49°C (120°F), closed containers may rupture under fire conditions
Protective Equipment: Full protective gear, self-contained breathing apparatus, avoid inhalation of any combustion fumes
Special Instructions: Cool containers with water, stay upwind, evacuate non-essential personnel
Personal Precautions: Use protective gloves, goggles, lab coat, avoid breathing vapor or mist
Environmental Precautions: Prevent entry into drains, sewers, waterways as far as possible; notify authorities if spill spreads uncontrollably
Methods for Cleanup: Absorb on sand, vermiculite, or inert absorbent, scoop up into chemical waste containers, ventilate area well, wash spill site after material pickup
Risk of Exposure: Mainly occurs if material escapes closed systems or handling facilities
Handling: Wear standard chemical-resistant gloves and splash goggles, keep containers securely closed, avoid all sources of ignition or static discharge, ground transfer equipment
Storage Conditions: Store in tightly sealed containers, cool, dry, well-ventilated area, away from heat, sparks, oxidizing agents
Incompatible Substances: Strong oxidizers, acids, alkalis, could react violently or degrade the product
Advice on General Occupational Hygiene: Keep food, drink, and tobacco away from chemicals; wash hands thoroughly after use
Control Parameters: No established occupational exposure limits for 2,6-dimethyl pyrazine; best to keep exposures as low as possible by local exhaust
Ventilation: Use laboratory fume hood or engineering controls for any significant work
Eye Protection: Safety goggles or face shield
Skin Protection: Chemical-resistant gloves, lab coat, long sleeves
Respiratory Protection: Wear an approved respirator if vapor concentrations approach nuisance levels, especially in enclosed spaces
Other Protection: Have eyewash stations and emergency showers nearby
Appearance: Colorless to pale yellow liquid
Odor: Distinct roasted, nutty, chocolatey odor
Melting Point: −1°C to 2°C
Boiling Point: About 169–171°C
Flash Point: Approximately 49°C (120°F)
Solubility: Slightly soluble in water; readily soluble in organic solvents like ethanol, ether
Density: About 1.03 g/cm³ at 20°C
Vapor Pressure: Not exceptionally high under standard conditions
Viscosity: Low, behaves similar to other small pyrazines
Reactivity: Not known for violent reactivity but will burn in presence of ignition
Chemical Stability: Stable under standard room temperature and normal storage practices
Hazardous Reactions: May react with strong oxidizers delivering heat; no polymerization issues expected
Decomposition Products: Combustion or heating leads to carbon oxides, nitrogen oxides, some complex pyrolysis products
Environmental Conditions to Avoid: Heat, sources of ignition, incompatible chemicals such as peroxides and strong acids
Routes of Entry: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Not highly toxic, but concentrated vapor may cause dizziness or headache, skin and eye exposure may sting or redden
Chronic Effects: No well-documented chronic effects, but best to avoid repeated unprotected exposure
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No evidence from animal studies or data classified as hazardous under standard regulations
Symptoms of Exposure: Eye, skin, and respiratory irritation, possible mild effects on central nervous system with large exposure
Ecotoxicity: Moderate aquatic toxicity possible, not highly persistent in environment
Persistence and Degradability: Not expected to bioaccumulate, breaks down slowly in nature through microbial activity and photolysis
Mobility: Low water solubility means little chance for wide groundwater dispersion
Other Adverse Effects: Large spills might temporarily harm aquatic organisms or affect local biological wastewater treatment
Disposal Methods: Incinerate in chemical waste facility compliant with local, state, and federal rules; never dump in general waste or sewers
Container Disposal: Empty containers should be triple-rinsed, offered for reconditioning or recycling as per local guidance
Local Regulations: Follow all environmental and waste disposal legislation specific to location of use
